Cleaning Up From Sunday's Fast-Moving Derecho
How will warming impact Minnesota? More flooding events. Flooding in places that rarely see flooding - more "drainage floods" as opposed to rivers overflowing their banks.
Check your homeowners policy - damage from flooding probably isn't included. I see no strong scientific evidence the warming well underway is sparking more tornadoes or hail, at least not yet. Higher dew points in summer; we're seeing a longer growing season and more erratic winter snows, but data linking high winds/big hail with a warmer, wetter atmosphere is inconclusive at this time.
Tell that to residents of Coon Rapids, where they had to call out the snow plows! Sunday's squall line probably fit the definition of a rare "derecho", with wind damage along a 250-mile swath or longer.
After refreshing 60s yesterday we should see 80s today with a slight risk of thunder. Storms become more numerous Tuesday as another hot front pushes the mercury up to 90F. Wednesday's storms mark the leading edge of cooler, drier air. By Sunday temperatures may hold in the upper 70s.
Enjoy any free A/C. I'm starting to suspect July will wind up stinking hot.
Photos from yesterday's severe thunderstorm outbreak:
"A Nasty Storm". The Star Tribune has more details on Sunday's severe weather episode across Minnesota and Wisconsin.
NOAA SPC has a complete list of Minnesota and Wisconsin hail and wind damage reports here.
Gradual Cooling Trend. Dew points reach the sticky 60s into Wednesday before a west breeze pushes tropical air out of Minnesota later this week. Temperatures may top 90F Tuesday if the sun is out for a few hours, but we'll all be enjoying cooler, drier air by late week and next weekend. Twin Cities ECMWF numbers: WeatherBell.
Heat-Related Ailments. Dry skin, rapid breathing and pulse, along with slurred speech and disorientation are all symptoms of heat stroke, which can prove fatal if not treated quickly and effectively. If in doubt, call 9-1-1.
Dress for Hot Weather Success. Although survival is probably a good place to start. Thanks to HealthTalkUMN at the University of Minnesota.

The Real Story Behind Elon Musk's $2.6 Billion Aquisition of Solar City, and What It Means for Tesla's Future - Not To Mention the Planet's. The longest headline on record? But more interesting background on what motivates Elon Musk, courtesy of Fast Company: "...These roof tiles are the latest component of Musk’s larger plan to wean us off fossil fuels. Inside the garage of each of these homes, he points out, is a Tesla vehicle and next-generation Powerwall, the sleek rechargeable battery Tesla developed in 2015 to store energy for household use. During the day, the solar shingles can generate electricity and recharge the Powerwall. After the sun goes down, the battery takes over, providing power independent of the traditional utility grid. “This is the integrated future. You’ve got an electric car, a Powerwall, and a Solar Roof. It’s pretty straightforward, really,” he says with a big shrug and a smile. “[This] can solve the whole energy equation.” Musk’s announcement is about saving the planet. But it’s also about saving SolarCity, the company his cousins, Peter and Lyndon Rive—who are in the audience—launched with Musk’s support in 2006 to bring solar power to the masses..."

Concussion Expert Says Extent of Brain Damage in Youth Football Players "Took My Breath Away". Here's a clip from ThinkProgress: "...While the impact of football on younger brains hasn’t been studied as comprehensively, scientists at the Mayo Clinic Brain Bank last year discovered evidence of CTE in 21 out of 66 brains they studied that belonged to males who played contact sports when they were young. Perhaps most alarmingly, they studied 198 brains in the bank that had zero documented history of participating in contact sports, and none of those brains showed signs of CTE. So while the research is still in the early stages, the connection between contact sports in youth and CTE later in life is pretty clear..."

Trump Wages Battle Against Regulations, Not Climate Change. Some interesting spin from PBS NewsHour; here's the intro: "While President Donald Trump’s beliefs about global warming remain something of a mystery, his actions make one thing clear: He doesn’t consider it a problem for the federal government to solve. Trump’s recent decision to pull out of the Paris climate deal was just his latest rapid-fire move to weaken or dismantle federal initiatives to reduce carbon emissions, which scientists say are heating the planet to levels that could have disastrous consequences. Trump is waging war against efforts to curb U.S. dependence on fossil fuels. He’s done that through executive orders targeting climate change programs and regulations, massive proposed spending cuts and key appointments such as Scott Pruitt as chief of the Environmental Protection Agency..."
